2d Sprites not turning out sharp in unity 3d terrain

Hello, im using some 32x32 sprites that i made some year ago and finally wanted to use in a game. First when i put them in to unity, they are really blurry. And i had to change the “filter mode” to Point. And they turned out sharp and pixelated as i wanted them. Then i added them in my terrain “Paint Details” To add some grass to my terrain. And they turned out blurry again. Any idea why? would appreciate it! Thanks
